Abstract: TITLE OF THE INVENTION:            A MOULD FOR CASTING AN ASSEMBLY ELEMENT FOR STEEL REINFORCED CONCRETE TRUSS-WORK PANELS     ABSTRACT OF THE DISCLOSURE:            An assembly element for steel reinforced truss-type panels is cast as a one piece unit and comprise  an upper and a lower chord plate interconnected by three, four, or six struts which extend out of the center of one plate and run toward the edges or corners of the respective other plate.          The struts are so positioned that the assembly element may be produced by mold casting.  The removal of a cast element is facilitated by a mold which has a lower bottom cap, an upper top base and laterally movable side wall sections.  A pair of lateral side wall sections interconnects a bottom cap portion and a top base portion to form a mold part.          Thus, the number of mold parts correspond to the number of struts in the element.

Abstract: CYCLE STEALING I/O CONTROLLER WITH          PROGRAMMABLE OFFLINE MODE OF OPERATION                 Abstract A dual mode microprocessor acts either as a front-end I/O controller processor relative to a primary/ host processor and device or as a secondary data pro-cessor having independent storage, processing and I/O capabilities.  Host software prepares device control block (DCB) arrays, which contain primary commands interpretable by the microprocessor and evoke these modes.  Each DCB contains a chaining bit permitting its interpretation sequence to be chained (or not chained) to another DCB sequence, and a mode bit defining either a high speed DI/DO (HS) mode of operation or a program-mable offline (PO) mode.  In HS mode the microprocessor conditions associated adapters to transfer a specified amount of data between the host memory and device, through a specified interface busing path and in a specified bit-parallel format.  The adapters perform this transfer in an autonomous manner, i.e., without assistance from either processor.  In PO mode the microprocessor directs associated elements to perform one or more programs of operations defined by secondary commands contained in a command list.  Such lists, prepared in advance in host system memory, are trans-ferred to the microprocessor's memory by special PO mode "LOAD" type DCB's, and interpreted in response to special PO mode type "START" DCB's.  A list transferred by one LOAD DCB may be repeatedly accessed at various positions by several START DCB's.  The architecture of the command list includes commands which permit the microprocessor to exchange data with the host and/or a device, perform arithmetic operations on data, perform bit and byte manipulative operations on data, and directly control the device interface.  PO mode se-quences are terminatable by the microprocessor in response to various internal and external conditions. Upon termination the microprocessor evokes either a DCB chaining action or a host system interruption for transferring concluding status, depending on the value of the chaining bit in the current (start type) DCB.

Abstract: ABSTRACT OF THE DISCLOSURE A pull-ring for an electrical device, such as a high-voltage fuse, which may be placed in a mounting. The pull-ring operates a latch, which is capable of holding the fuse closed in the mounting, only when it is reciprocated. The pull-ring is pivotable independently of its reciprocation without affecting the condition of the latch. Accordingly, when a trunnion on the device is in a hinge of the mounting and a pushing force is applied to the pull-ring with a tool to close the device, the natural decrease in the interior angle between the tool and the device can rotate the pull-ring without preventing the latch from holding the device closed. Further, whether the pushing force or a pulling (opening) force is applied to the pull-ring, the direction of application of the force may be adjusted or may naturally change before, during, or after such force application with affecting the ability of the latch to hold the device closed. The tool may, therefore, be either a non-grasping tool (a "hot stick") or one (a "shotgun stick") capable of grasping the pull-ring. In the latter event, when the tool grasps the pull-ring and the trunnion is out of the hinge, the pull-ring is biased to a pivotal orientation whereat the trunnion is presented for convenient insertion into the hinge upon manipulation of the tool.

Thus, with a laterally directed component of gravity aiding in the separation of dielectric items from electrically conductive items the commingled materials may be deposited anywhere transversely on the input end portion of said inclined surface, thereby increasing the input feed capacity of the transversely inclined ramp-type separator as compared to the restricted input feed capacity of a conventional ramp-type separator of nonferromagnetic materials.

Abstract: ABSTRACT An article dispenser for dispensing articles from a vending machine is disclosed.  The article dispenser includes an article storage area which has a bottom opening through which articles are dispensed and a front opening through which the articles are loaded to form two vertically adjacent rows.  An article dispensing mechanism dispenses the lowermost articles stacked in the storage area through the bottom opening.  This article dispensing mechanism includes a rotatable shaft which vertically extends within the storage area to divide the storage area into the two vertical rows or columns.  A control plate is fixed to the lower end of the rotatable shaft to control the operation of a pair of doors positioned below the two vertical rows of articles.  As these doors open and close upon rotation of the rotatable shaft, the lowermost articles in the stor-age area are dispensed.  The article dispensing mechanism further includes an article holding mechanism located at the lower end of the storage area to hold the articles in both rows, except the lowermost articles, in a stacked position during the opening of the doors.  The holding mechanism includes opposite holding surfaces which frictionally engage adjacent articles in both rows to hold these articles between the holding surfaces and the inner surfaces of the storage area.

Abstract: Abstract:      An electrically operated light control device includes an electrostatically actuated element that comprises, in superposition, a stationary electrode, an electrode move-able between a position overlying the stationary electrode and a position removed from the stationary electrode, and a non-conductive element between the electrodes for keeping the electrodes electrically separated.  The moveable electrode is in the form of a sheet of flexible material having one end fixed with respect to the stationary electrode and the opposite end free with respect to the stationary electrode.  This sheet of flexible material has a permanent stress which biases the sheet into a curl away from the stationary electrode.  The element is characterized by the fact that the non-conductive element comprises a sheet of electret material that is capable of retaining an electrostatic charge to provide an electrostatic force to act on the moveable electrode.  The element is actuated by the resultant sum of the electrostatic force provided by the electret material and the electrostatic force created when an electrical potential is applied to the electrodes.
